Be it known that 1, Low m (loom it fii iii zen of the Umtfl Statesresuimg et Ben ninggton, in the county of Bennington,

of Vermont have inventeoi a new and useftui Device for Eitroppingmafetyflitemrs; and 1? do hereby declare the following to be e :ifoii,clear, anti exact description oi? the invention, such as will enableothers skiiieti in the wt to which it apperteins to mete end use thesame, This invention is e. device c iesigneci fer holding seiety rezorblades so that they may be stroppeti with 'ifztciiity.

its principei object toprovide it device for pet-teeming: the stroppiegoperation that Wiii eneoie both sides of the flitting; e oi? e safetyremihimie to be stropperi. W. out the necessity of having to change thetime in the he] AJQUiLiM-lt' objec s to provide it simpie but etiieientmeans 1:01 attaching the bietic in the hoider. i

third. object is to provide :1 pair oi? lOiiS that Wiii siide during"the strokes of the stropping operation but wiii turn at the reversal ofeach stroke so as to bring the desired edge into contact with thesti'opv A fourth object is to provide, in combination With the bizuieholder e strep support having iongit'l'ldina-i tracks on which the roiisof the holder may siidei Although but one design is shown for thepurpose of setting forth this intention, the invention. is not to belimited to this design. The right is reserved to make any changes oralterations that practice may require, so long as such changes orattentions fail Within the scope of the subjoined cieims.

non to keep its iteee underneath arms 4 near their inner ends, theshoulder portions 21 of the studs operating as spacing means to keep theurine in elinement with the feces of the rolls 6. (Janeentrio with thepoint of oscilletionfthe arms 10 are provided with slots 22 throughWl'llCl the studs 7 pass. These slots permit the oscillation of the arms10.

The case 23 is designed to contain the blade holder, the recess in theupper face of block 25 end in which the rod 3 rests being designed toprevent the holder from shitting therein. Cover 24: is connected to thecase by the hinges 26, the strep support 2'? being positionedlongitudinally in the cover and centrally disposed with reference to theWidth. Below the strop support the metallic strips 28 are secured, oneon each side of the support and running the length of the cover. Thestrep 29 is held oil-top of its support by having its ends engage underthe golre members 30 which have right angled ends at the ends of theirlegs by which they are attached (by soldering or other menus) to themetallic strips 28.

To perform the sharpening operation the razor blade is attached to theplate 11, so that it will be held thereon by the heads of the studs 15,the end of the blade abutting the pin 19 to keep the blade in positionun der the heads of the studs, as previously described. The holder isthen pieced so that the yoke l straddles the strep support 27 when therolls 6 will be in position to slide on. the metallic strips 28- und theblade Will be above the strep. v

On the forward movement the rolls 6 by contact With the metallic strip28 will tend to turn causing the pins 8 to niovenp'vvurdly carrying withthem the oscillating" arms 10., The arms 10'by engagement with the pin13 operate to turn the plate 11 in e direction the reverse of thedirection in which the rolls 6 are moving, thus bringing one edge of theblade against the strop. v Jhen the blade touches the strop furthermovement of rolls 6 on the oscillating arms 19 is stopped, the

rolls 6 for the rest of the movement sliding alongthe strips 28 end theedge of the blade dragging on the strop. On the return move went theopposite edge of the bin-dc will he brought into contact with the strepas e result of reversed. mover imparted to the rolls 6 end 0S2;

arms 10 by the reversal oi movement imparted to the whole device.

The device may be turned over so as to sharpen edges that werepreviously uwuy from the strep, the some cycle of operations beingperformed by the several component parts, whether the blade 16 is facingthe strep or whether the plate 11. faces it.

l i hut is claimed is:

1. in a device for sharpening safety razor blades, a yoke having" ehandle attached thereto, rollers having integral studs for pivotellyconnecting them to the yoke, spertured studs integral with the inner"faces of the rollers, it plate having pins in pivotal engagement wi hthe upcrtured studs, oscilleting arms pivotully connected to the yoke,pins on the rollers adapted to engage the os cilluting H1 118, pins onthe plate engaging the oscillating" arms, end means for attachthe razorblade to the plate,

2. In a device for sharpening safety razor blades, e yoke having ahandle attached thereto, rollers having integral studs for pivotallyconnecting them to the yoke, apertured studs integral with the innerfaces of the rollers, a plate having pins in pivotal engagement with theepertured studs, oscillating arms pivotally connected to the yoke andhavingcurved slots which permit the arms to me us without interferencefrom the opertured studs and further having; straight slots profcctingsubstantially at right angles to the curved slots, nson the rollerseclipted torngi age the iight slots on one side of the curved slots, onthe plate adapted to engage the straight slots on the other sides of thecurved slots, and means for at tuching" the razor blade to the plate.
